General description The VOS617A series has a GaAs infrared emitting diode emitter,which is optically coupled to a silicon planar phototransistor detector, and is incorporated in a 4-pin 50 mil lead pitch mini-flat package. It features a high current transfer ratio at low input current, low coupling capacitance, and high isolation voltage. The coupling devices are designed for signal transmission between two electrically separated circuits.
FEATURES ●High CTR with low input current ●Low profle package (half pitch) ●High collector emitter voltage, VcEo= 80 V ●lsolation test voltage = 3750 VAMS ●Low coupling capacitance ●High common mode transient immunity ●Material categorization:

The VOS617A-4T is an optoisolator transistor, also known as an
optocoupler or photocoupler.
Optoisolators are electronic devices that combine an optical
transmitter (LED) and a photodetector
(transistor) to provide electrical isolation between two circuits
while allowing the transfer of signals
or data through light.
Here are some general specifications for the VOS617A-4T
optoisolator transistor:
Isolation Voltage: This refers to the maximum voltage that can be
applied between the input and
output sides of the optoisolator while maintaining electrical
isolation. The specific value would depend
on the datasheet of the component.
Input Type: The input side of the optoisolator typically consists
of an LED (Light Emitting Diode) that
emits light when forward biased.
Output Type: The output side of the optoisolator generally includes
a phototransistor or photodarlington
that responds to the light received from the input side, allowing
current to flow through it.
Package Type: The optoisolator may come in various package types
such as through-hole (e.g., DIP)
